Why the silicon metal can be used in semiconductor industry?

 

Because of the band gap energy at 300K of the silicon metal , it is confirmed as an important semiconductor material. It has a negative temperature coefficient of resistance , since the number of free charge carriers increases with temperature. The electrical resistance of single crystal silicon significantly changes under the application of mechanical stress due to the piezoresistive effect.

 

 

Applications:

 

- Used in semiconductor devices and incorporated in microchips

- Used in alloy industry and metallurgical industry

- Used in manufacturing of glass

- Used in making ceramic products

- Active ingredient in cement

-  The desiccant silica gel water imbibition is strong, the commonly used some foods
